1Be it fknownthat LGEoEcE'W. TTEEsoN, citizen of 'the `1United States, residing -at Seattle, `in the county of 1' King-and Statef'o'f Washington, have invented a certain new and useful :Improvement -in Apparatus vfor Removing T'Sediment from f Catch-'Basins of Sewers, of'whichthe following Ais yaspeeifica-tion.

My invention relates Atto improvements in apparatus for removing y'sediment from catch-basins of sewers, and the `object of my invention fis to provide y#apparatus 1by wliic'h-'theforce of water underfpressure may be employed to agitatethe sediment which has accumulated ina catch-basin of a=sewer and Ythen to carry f' such Vsediment* upwardly into lasettling receptacle that is Iaccessible fromthe surface o'fa street, within which settling receptacle said sediment lmay lbe precipitated later to be removedtherefrom, whereupon-such water, now separated from the sediment mlayfbe conducted downwardly from 'said settling` receptacle into` said catchbasin.

f1 accomplish this objectby devices Iillustrated in vvthe accompanying drawings wherein Figure 1 `isa -plan viewof asettling receptacle with its cover removed, showing such rreceptacle disposed in yafstreetbetween two man holes that' eXtend downwardly into thecatch-basin of a sewer; FigfZ `1s alview in vertical section, on broken-line m, 'of Filg. 1,'s'howingsa1dman hole land a crosssectionf'o'ffa catch-basin; Fig. 3l 1sI aview in -crossisectiom on broken liney y, y, of Fig. `1,

'4 is aview in -horizontal sec- `broken line a, *e of Fig ,fandFigflis aview in vertical section onfbroken line l@0,2120 of Fig. l1, showing therela'tivepositions ofthe various devices associated -to embody my linvention.

Referring to the drawings, throughout which flile reference numerals designate like parts,'' 6 'and `7 "designate man 'holes l'disposed to rjextend downwardly from the surface r8 lof 'fstreet f'each l into 'a different f end portion of -a catch-basin 9, each fend fof which catch-basin A-9 lis connected with fa. sewer "pipe, as rsewer pipes 10 and 11 Disposed between the :upper ends of `the man holes v'6 and I'7 is 'a 'l settling receptacle 12 which l.is v'provided with a iremovable cover vl13 whose ftop surface 'fis' iin 'the same plane with 'the top surfaceffS f of va street.

5P1"efe1ably,the Iwalls of said receptacle 12 are fmlade integral ff fconcrete, las Lare also ther walls ofthe-'man holes 6 "-and''? and the catch-lo'asinl 9.

The receptacle 12 is fprovide'd with :a fpartition 14disposedtoextend lfrom its zend w-all,f adjacent vto themanfhole 6, toward its i opposite fend vthroughout 'thrce quarters fo'f the lengtlrof lsaid'ieeceptaele y12, 'said partition 14 being-spaced from the sidewall that is nearer saidl man lholes f6 and 7 ,das shown more clearly in Fig. 1, wherebyiis formed anarrowpassagewa'y 115.

That lend of I-the partition '124 which Vils nearer tothe manhole l7 `connects 'withthe end ofla partition '16 which `extends'therefromf directlyy acrosst the receptacle 12f`to"'the manhole 6 are f two transversely disposed partitions 18-and 19 which provide `the l'receptacle i12 with 'three ladditional vvconi'partments 20, '21 Iand 22.

Thepartition "18, on fthat end portion fo'f it adjacent to the/partition14,*lia`s"arectan gular portion removed from its 'upperfpafrt to form Ta passageway l23 -through yfwliitfzh water lmay pass from ythe compartment 521 tothe compartment'QO when {thecompartand lthe partitions A16 `and 19` are Lprovided with similar passagew-ays, ias passageways 24 and 'i Q5 respectively, over I'their end portions adj acent "to f the f opposite side wall of said receptacle '-12 y"whereby 'when water fis conducted into the fcoinpartmenti siichff and when such water rises therein above three quarters of the height of the partition 16 it will iow through the passageway 24 into the compartment 17, and when such water rises therein above the end of the floor of the passageway 15 then it will flow into the passageway 15, such course of said Water being indicated by arrows in Fig. 1.

Extending upwardly from the central portion of the bottom of the catch-basin 9 to a line higher than the sewer pipes 10 and 11 is an. integral partition 26 which extends longitudinally within said catch-basin 9 with its ends disposed at the same distance L from the adjacent one of the sewer pipes 10 and 11, and each of the ends of said partitions 26 is provided with a vertically disposed groove, as grooves 27 and 28, and the end walls of the catch-basin 9 are each provided with two similcr grooves (as grooves 29 and 30 and grooves 31 and 32) spaced from each other as more clearly shown in Fig. 4.

Within the grooves 23 and 31 is removably disposed a gate 33, and within the grooves 27 and 29 is removably disposed a similar gate 34, whereby water flowing between the sewer pipes 10 and 11 may pass only on one side of the partition 26.

The gate 33, may, however, be removed and inserted within the grooves 28 and 32 and the gate 34 may be removed and inserted in the grooves 27 and 30, whereby water flowing between the sewer pipes 10 and 11 would flow on the other side of said partition 26, thus, the catch-basin 9 ma-y first be cleaned in that part of it on one side of said partition 26 and then be cleaned in that part on the other side of said partition 26.

Obviously, after the catch-basin 9 is cleaned on both sides of the partition .26 the 'gates 33 and 34 should be removed so that water of the sewer pipes 10 and 11 may 'low on both sides of said partition 26.

Within the man hole 6, adjacent to the wall thereof, is a ladder 35 -by which one may descend to the catch-basin 9.

Disposed within the catch-basin 9, at one endv thereof, is a hydraulic elevator 36 whose delivery pipe 37 extends vertically upward adjacent to the vertical wall of the man hole 6, and the upper end of said delivery pipe 37 terminates in an angular portion 38 which leads into the upper portion of the compartment 22l whereby an operation of the hydraulic elevator 36 will act on the sediment and water contained in the catch-basin 9 to elevate such sediment in the form of muddy water and deliver it into the compartment 22.

Water under pressure for operating the hydraulic elevator 36 is conducted from a street water pipe 39 through a valve-controlled pipe 40 disposed in the upper portion of the man hole 6, which valve-controlled pipe 40 is connected by an elbow 41 with a pipe 42 that extends downwardly within the man hole 6 where its lower end is connected with the hydraulic elevator 36, whereby, in

end of the passageway 15 adjacent to thel man hole 6, is an outlet pipe 43 which connects with an elbow that is connected to the top end of a pipe 44 which extends downwardly within the man hole 6 to a point near the bottom of said man hole 6 where its lower end is connected with a swivel joint 45 to the bottom end of which is connected an angular nozzle 46 which is thus rotatively movable to adaptit to be swung to deliver water (that may iow from the passageway 15) into that side of the catch-basin 9 that at the time is to be cleaned, the impact of such water serving to stir up the sediment deposited on such side of the catch-basin 9 to facilitate the operation of sucking such sediment into the hydraulic elevator 36.

When the muddy water containing the sediment from the catch-basin 9 iiows into the compartment 22 such muddy water rises therein until it flows over the end portion of the partition 19 through the passageway 25 into the compartment 21 and such water in passing through the compartment 22 precipitates a large portion or' its sediment within such compartment 22 and such water rising within the compartment 21 will flow over the end portion of the partition 18 through the passageway 23 into the compartment 20, and in passing through the compartment 21 it will precipitate much of its sediment therein, and such water rising within the compartment 20 will flow over the end portion or' the partition 16 through the passageway 24 into the compartment 17 leaving another portion o its sediment within the compartment 20, then such water will rise in the compartment 17 to flow into the passageway l5 and during its flow through said compartment 17 practically all of the remainder of its sediment will have been precipitated within said compartment 17 so that such water upon entering the passageway 15 will contain little if any sediment, and then such clean water will flow through said passageway 15 into the outlet pipe 44, thence through the nozzle 46 into that side of the catch-basin 9 that is being'operated upon.

After the catch-basin has been thoroughly cleaned and its sediment deposited in the several compartments of the receptacle 12 the head of water from the water pipe 39 is shut olf by closing the valve in the valvecontrolled pipe 40 and thereupon the gates 33 and 34 are removed and the covers of the man holes 6. and 7 may be replaced, after which at a convenient time the cover 13 of the receptacle 12 may be removed and the sediment deposited in the several compartments 17, 20, 21 and 22 may be shoveled into a dump wagon and carried away to a desired dumping ground, and after such sediment is thus removed from the receptacle 12, then, its cover 13 may be replaced to form a part of the surface of the street. y

Obviously, changes may be made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.

What l claim is:

1. The combination with a sewer containing a catch-basin, of a settling bed built in in connection with the sewer at or near the ground level, a hydraulic ejector elevator for removing deposits from the catch-basin upwardly to the settling bed, and a return for water from the settling bed to the sewer.

2. The combination with a sewer catchbasin, and a man-hole opening into the same, of a settling bed built in at or near the ground level adjacent the man-hole, a hydraulic ejector elevator extending within the man-hole for removing the contents of the catch-basin upward to the settling bed, and a return for water from the settling bed to the catch-basin.

3. The combination with a sewer containing a catch-basin, of a settling bed built in in connection with the sewer at or near the ground level, a hydraulic ejector elevator for removing deposits from the catch-basin upwardly to the settling bed, and means for returning water from the settling bed to the catch-basin and for utilizing the return stream to agitate the contents..
